When older houses were electrified before WWII it was seen as a replacement for gas lighting rather than as a general utility with multiple uses. It was completely normal for only a lighting circuit to be installed upstairs, though there would usually be a single power socket fitted in the living room. Irons and electric blankets were routinely plugged into the light socket, as were sewing machines.

These houses only received proper power circuit ring mains during the 'great rewiring' of the 1960s.

That bathroom heater looks absolutely lethal John. I hope she doesn't have a bath with it turned on!
